Quandary... I have 65 acres with a decent number of 2-3 inch trees. They are tulip poplars which grow in clusters. Tractor is a Kubota
L6060. Found a 6ft brown tree cutter for a good price which seems a bit on the big side but would demolish the trees. Otherwise I could go with a bush hog 306 or similar heavy duty cutter. Any experience with anything similar anyone can share. Thought also of getting a loader mounted tree shear for the stuff that is a little too big.
I had a recent thread on here about clearing a pasture and there were a number of suggestions. My tree 'problems' are sweetgums and water locust. I am told that both will come back if not treated with herbicide, so, be aware of that. I am going to do that.
As for my removal method, I have been doing it with chainsaw and also trying to pull them up by the roots, which works (chain and tractor) but it's slower going than I wish because I have a lot of trees. With 65 acres, your number of trees might be even more.
I found a 'brush grabber' gizmo online and it looks interesting for quick attaching to sapling (end of a chain) so you can pull them up by the roots. It looks like it would work. We just tie a chain on but I think the brush grabber would be faster and more efficient. Cost looks to be $200 to $400 depending on size.
You can also buy an attachment for a FEL that allows you to dig up saplings by the roots. That looks like it would work.
As for my choice, I just hired a mulcher operator. He is a bargain at $75/hour. Two years ago, I hired a mulcher guy who was across the road working on a neighbor's land and I asked him to come to my land for three hours and he did. I just wanted to see how fast he could clear a trail in dense forest. In three hours, he did what would take me weeks clearing a trail manually with chainsaw and brushcutter and machete. He charged $90/hour. So, I am eager to get the new guy for $75/hour. I will have him mulch all these sweetgums in the pasture and also blaze some new trails in my woodlot. I will not have him mulch the water locust trees as they have horrific thorns and I will pull them all up and burn them to, hopefully, get rid of all the thorns, which are long as your finger!
I have witnessed what a Brown tree cutter can do. It can, generally, do what a mulcher can do. But I saw it on a armor-plated tractor for working in the woods. As others said above, you need horsepower.
